OshwiPin: DIY PINS
Creation of OSHWDem mascot brooches (OSHWi, the octopus) made with felt, LEDs and conductive thread, during OSHWDem 2019.
The idea is to give an introduction to e e-textiles and soft circuit basic notions for anyone who knows a lot or a little about electronics.
We will provide a kit of materials with everything necessary for its preparation, and the BricoLabs volunteers will be on hand to help you make them, so that all the participants can take them home finished.
That way, we will help to spread the image of OSHWDem and promote open source technology to the general public.

Tricks on sewing with the conductive thread:
- Cut the conductive thread into small pieces, because in longer ones it becomes more entangled, among other problems (entanglements, thread twist is undone, etc …) and in addition, I remember the teachings of my mother: “Long thread, small seamstress ”.
- Use thimble: “Seamstress without thimble, sew little and sew badly”. Thank you for keeping my fingertips safe, mom!
- Needle with large eye (because the thread is thicker than those of sewing fabrics), but not too much, because it does not enter through the holes of the snap fasteners.
- And needle with a fine point (because those with a round tip, as they are usually those with a large eye, do not puncture well in the tissue and make stitches difficult).
- In thick fabrics such as felt, so that the stitch is not visible on the right side of the work, it is best to sew upside down and puncture only up to half of the fabric, so it is a cleaner job on the right side.
